Hello, I am new to this forum. I have had a small spinning composter for a while now. I made some partially composted material last year. This year I started a few weeks ago. I have a lot of "brown" material that is very carbon-heavy (twigs, shredded paper, dried leaves). My only real nitrogen sources have been kitchen scraps, used coffee, and leaves from fresh green weeds. My compost is still cold (66 degrees F to be exact). I was thinking of ordering urea crystals, ammonium, or blood meal to throw in there to provide some nitrogen. Has anyone tried this? How much would you use? Would you dilute it in water and pour it in? Thanks!
